Electric Vehicles

The Best Part of an EV Is When You’re Not Driving

That enormous battery can do a lot more than propel your car down the road.

Many new cars and trucks come with modes to optimize driving. Anyone who’s watched an episode of Top Gear has seen the hosts extoll the virtues of sport mode, which makes steering tighter and more responsive, or off-road mode, which allows a 4X4 to better cross muddy terrain.

Electric vehicles have their own performance modes, like Tesla’s “launch control” that sends the Model S screaming off the starting line. But some of the most interesting things an electric car can do happen when it’s sitting still. Because the giant battery along the bottom of an EV can do a lot more than propel the car down the road, EV-makers have realized they can use this reserve of electricity to create quality-of-life features that wouldn’t be possible in gasoline cars.


There used to be a set of no-nos when it came to sitting in the car. Running the air conditioner, listening to music, or leaving the headlights on without the motor running would tax the boxy 12-volt battery found under the hood. Overdo it and you might need to talk a stranger into a jump-start, something I learned the hard way when I was a pre-teen and depleted the battery in my parents’ Pontiac minivan waiting for them to escape a meeting.

Cars got better about this issue as the years went by, but electric vehicles nearly negate the problem entirely. Consider the modern sin of leaving one’s pets behind. States like California have laws against leaving an animal unattended in a hot car, and for good reason — without ventilation, a vehicle interior can get even hotter than the outside air. Combustion cars can’t (or shouldn’t) keep the air conditioner on without also running the engine, which prevents you from keeping the pooch nice and cool.

Not so in the EV age. Rivian and Tesla both have pet modes that will use the battery’s electricity to run climate control while you run into Walgreens while Walter the terrier stays behind. Both brands display a cheery cartoon dog on the large center touchscreen, alongside a message to would-be Good Samaritans that the cabin is holding a pleasing and pleasant temperature.

Pet modes come with safeguards. They can’t be used if the battery is too low, for example, to prevent a scenario in which the car runs out of juice and can no longer cool the dog. Still, they can’t guard against the fact that this new technology runs against a societal stigma against leaving pets in the car. (I keep paper signs in my Model 3 that read “AC ON, DOG IS FINE” to dissuade passersby from breaking a window or calling the authorities.)

Humankind benefits from EV climate features, too. Leaving the heat or AC on indefinitely bleeds a few miles of range from the battery, but doesn’t endanger your ability to get the car started again. You could even sleep in the comfort of a climate-controlled room on wheels (or park cranky kids in front of Encanto on the touchscreen). Tesla offers Camp Mode for this very purpose, promising that an entire night uses only about 10 percent of the battery. Rivian’s is especially high-tech: It tweaks the truck's suspension to keep it level on uneven ground, and allows owners to shine their headlights to illuminate the campsite, a definite battery-killer in a combustion car.


These applications are mere extensions of the familiar, giving traditional car accessories a lot more staying power. The transformative potential of driving a battery on wheels would be the ability to use that electricity supply for, well, anything you want.

The technical name is bidirectional, or two-way, charging. The Ford F-150 Lightning includes this feature, and its advertising touts that the electric truck can plug into your home to provide days of backup power in the event of a blackout. Tesla’s initial round of Cybertruck marketing proclaimed that the steel beast would become the mobile heart of a jobsite, with power tools running on battery power thanks to an array of outlets on the vehicle’s exterior.

Two-way charging makes an EV more technically complex, since the direct current (DC) power the car uses would need to be transformed back into alternating current (AC) to run other applications. But the possibilities are enticing for the electric vehicle owner. EVs that remain plugged in while not in use could feed energy back onto the electrical grid, just as homes with solar panels can pass on excess energy. Such a setup could help avoid blackouts by creating an alternative source of stored electricity — not to mention generate income for EV owners who are technically selling power back to the grid.

It is coming, if slowly. Tesla, having resisted bidirectional, said this spring that it would adopt the technology within a couple of years. Other automakers have introduced some limited versions of it.

Someday soon, then, your car, flashlight, and backup generator may be one and the same.

Q&A

Why the Wilderness Society Backs a Data Center Moratorium

Talking with Dan Hartinger, the land conservation group’s senior policy director.

The Q&A subject.

This week’s Q&A is with Dan Hartinger, senior policy director for The Wilderness Society, a prominent land conservation organization in D.C. that this week called for a moratorium on data center development on public land. The public statement was relatively scant on details about the group’s stance, and a decade of reporting on policy in Washington has taught me that its positions are quite influential, especially in more traditional outdoor recreation and conservationist circles that are also often bipartisan. So I reached out and asked if someone could further explain the society’s position, and Dan obliged.

The following chat was lightly edited for clarity.

Data Center Outrage Catches Up to Renewables Outrage in Michigan

Plus more of the week’s biggest development fights.

1. Central Michigan – I regret to inform you of this back-and-forth between candidates running for Congress and a would-be constituent because it’s a warning sign for the renewable energy sector (and sort of broke my brain).

  • This week brought the first and likely only debate between Rep. Tom Barrett and Sunrise Movement cofounder Will Lawrence, who are locked in a tight contest over the Michigan 7th congressional district. As I’ve written, their race is a must-watch not only for control of the U.S. House but also the political fortunes of the data center sector.
  • The debate contained a remarkable exchange: Moderators played taped remarks from Paula Caltrider, identified as “a local resident” in the city of Mason to ask the candidates a question about data centers. Instead, she offered a comment. “You know, you can’t be a part of this no data center movement without renouncing the large solar farms and dangerous battery storage facilities that power these data centers.” (Quick TL;DR on Caltrider: She’s been quoted in national media coverage of the data center backlash and last year won a legal settlement after allegedly being fired for refusing a vaccine mandate.)
  • Barrett then ran with Caltrider’s baton. “I appreciate Paula linking these together, the stripping away of local control that took place in pursuit of this Green New Deal agenda in Lansing that took away control from communities” – a reference to the state’s primacy law that other Michigan Republican candidates have opposed.
  • Lawrence, whose support for a federal data center moratorium made him a national political test case, did not take the bait, nor did he criticize renewable energy. Instead, this part of the debate became a tit-for-tat about whether the sitting congressman once backed tax breaks for data centers. “He stuck his finger up into the wind, saw which way it was blowing, did a complete 180 on this issue,” Lawrence said. Then Barrett and Lawrence got into a confusing back-and-forth about whether the Inflation Reduction Act was a giveaway to data centers.
  • To the best of my knowledge, this is the first time the Data Center Trojan Horse has reared its ugly head on any kind of prominent debate stage, but it won’t be the last. For example: The Wisconsin gubernatorial debate is Oct. 21, and we’ve warned you about that one.

2. Doña Ana County, New Mexico – I suggest you pay closer attention to the federal permitting fight playing out over Oracle’s Project Jupiter.

The Data Center Backlash Is Coming for Permitting Reform

The Senate’s compromise bill enters the chat at a moment when federal land and anti-pipeline advocates are already quite activated.

The AI data center backlash is getting louder in D.C. ahead of the midterms – and it’s poised to collide head-on with the new permitting reform deal being negotiated in Congress.

This week, major environmental advocacy organizations are taking large public steps to lean in on the data center fight. The League of Conservation Voters and Natural Resources Defense Council, I’ve been told, are imminently announcing a $250,000 ad buy in the Washington, D.C. market focused entirely on decrying fossil fuel-powered data centers and Trump administration policies to speed up their construction. The Wilderness Society, a prominent land conservation organization, announced it now supports a moratorium against data centers on “public lands” focused on the roughly half billion acres under the Interior Department’s stewardship. And Earthjustice on Thursday did a detailed report claiming that 80% of the data centers under development “bringing their own power” are going to rely on gas generation.
